Problems solved by technology

The basic method is to use appropriate tools to thoroughly rinse the nasal cavity, remove allergens, germs, inflammatory secretions and other dirty things in the nasal cavity, eliminate the basis for the continued development of inflammation, and eliminate the edema and swelling of the nasal mucosa. Restore the normal physiological function of the nasal cavity, but only relieve symptoms for organic lesions
The main components of nasal washes commonly used in clinical practice are physiological sodium chloride or isotonic sea salt water. However, the biggest problem with this type of device is that the nasal cavity dries quickly after nasal washes are rinsed, and the moisture retention is very short. times, the patient is very inconvenient

Abstract

The invention provides an antiallergic nasal medicine composition with high moisture retention and preparation methods and applications thereof. The composition has high moisture retention and no irritation to a nasal mucosa. The composition comprises levocetirizine, azatadine, loratadine, ebastine, setastine, bilastine, clemastine, mizolastine, epinastine and moxifloxacin which are antiallergic medicine as main medicine, wherein the main medicine can be salts or free alkalis, sea salt as an osmotic pressure regulator, and a mixture of sodium hyaluronate and glycerin of different molecular weights as a moisturizing excipient. Plant essential oil can be contained in the composition. Preparations can be an aqueous solution, a cyclodextrin-coated suspension or a nanosuspension. Dosage forms include spray, aerosol and nose drops. Main indications include nasal dryness, runny nose, nasal itching, nasal obstruction and the like due to allergic rhinitis.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a highly moisturizing anti-allergic nasal pharmaceutical composition, a preparation method and application thereof. Background technique [0002] Allergic rhinitis is a kind of allergic inflammation, also known as perennial allergic rhinitis, vasomotor rhinitis. The main clinical manifestations are paroxysmal nasal itching, dry nose, sneezing, a large amount of watery nasal discharge during acute attack, less and thicker when relieved, and mucopurulent, intermittent or persistent, unilateral or bilateral nasal congestion in concurrent infection , hyposmia or disappearance, headache, tinnitus, tearing, hoarseness and chronic cough. Systemic symptoms include headache, loss of appetite, easy fatigue, memory loss and insomnia. [0003] The clinical symptoms of rhinitis are different, and they are extremely harmful. When the physiological function of the nasal cavity is...
